Police are today examining an amateur video tape apparently showing a man with a backpack entering a Bali restaurant seconds before one of three suicide bombings on Saturday.
A top anti-terrorism official said the investigation into the attacks, which killed up to 27 people and wounded 125, was focusing on Islamic militants blamed for previous bombings in Indonesia.
Investigators released video footage last night of a man in a black shirt and jeans strolling into a restaurant on the resort island, followed almost instantly by an explosion.
Three separate bombs tore through restaurants packed with evening diners, many of them foreign tourists. Two were outdoor seafood eateries on Jimbaran Beach and one was a steak bar at Kuta Beach, an area surrounded by popular shops.
The nearly simultaneous Bali explosions came almost three years after al-Qaeda-linked Jemaah Islamiah (JI) militants bombed nightclubs in Bali, killing 202 people, mostly foreign tourists.
A top Indonesian counter-terrorism official confirmed that JI was the prime suspect for Saturday's attacks, although he could not confirm whether it was the only suspect.
